LATHE.

SPECIFICATION forming part of Letters Patent No. 308,924, dated December9, 1884.

Application filed January 21,1884. (No model.)

To all whom it may concern.-

Be it known that I, RoswELL Looms PEA- BODY, of Waltham, in the countyof Middlesex, of the Commonwealth of Massachusetts, have invented a newand useful Improvement in Lathes; and I do hereby declare the same to bedescribed in the following specification and represented inthe'accompanying drawings, of whiol1 Figure 1 is a longitudinal section;and Fig. 2, an inner end elevation, of alathe head-stock provided withmy invention, the nature of which is defined in the claim hereinafterpresented.

My improvement is to enable the arbor of the headstock to bereciprocated, swung, or moved laterally as well as revolved, such beinguseful for grinding or various other purposes.

In the drawings, A denotes a lathe arbor supported in a head-stock, B,which is pivoted on a cylindrical rod, 0, duly extending horizontallythrough and fixed in pedestals D, supported in the lathe-bed E.

, From the above it will be seen that the head-stock with the arbor canbe reciprocated or swung laterally, the extent of such movement beingdetermined by suitable means, or cars a a, projecting from thehead-stock, and ears I) b, projecting from the pedestal,as shown in Fig.2. The arbor has fixed on it a pulley, c, to which and another pulley,d,-rcvolub1e on the rod 0, an endless belt, 6, is applied, the pulley dbeing wide enough to receive a. driving-belt. v

From the above it will be seen that the arbor of the lathe head-stockmay not only be revolved, but while in revolution may be moved laterallya short distance each way beyond a vertical plane passing longitudinallythrough the axis of the red C.

There are other Ways in which the head stock or device for supportingthe lathe-arbor may be adapted so as to be capable of being reciprocatedlaterally while the arbor may be in revolution. I therefore do notconfine my invention to the precise way shown and described.

I claim The combination of the pedestals D, supported on the lathe-bedE, and provided with the rod 0, as explained, with the lathe-arborheadstock B, pivoted on said rod, and with mechanism viz., the pulleysand endless bandfor revolving the arbor, all being essentially as setforth, and being to enable the arbor to be revolved, and while revolvingto be moved or reoiprocated laterally of it, as explained.
